Regional coastal sediment transport processes
influence the evolution of sedimentary environments to varying degrees
depending on temporal and spatial response scales. A primary focus for
Applied Coastal personnel is quantification of historical trends in
shoreline position, bathymetry, and beach profile change at varying
spatial and temporal scales. This has been accomplished by developing
innovative strategies that take advantage of state-of-technology
advances in surveying, GPS, computer mapping, and GIS. Topographic and
hydrographic surveys of coastal and nearshore environments provide a
direct source of data for quantifying system response. Applied Coastal
uses these data (historical maps, photogrammetric surveys, GPS surveys,
beach profile surveys) to evaluate coastal change trends at various
sites along the U.S. coast (Louisiana, Mississippi, Florida, Georgia,
Maryland, New Jersey, New York, Washington) in relation to normal
incident coastal processes, storm impacts, relative sea-level change,
and human modifications of the coast.
Hydrographic surveys of regional nearshore morphology
provide a direct source of information for quantifying changes in
seafloor elevation. Comparison of digital bathymetric data for the same
region but different time periods provides a method for calculating net
movements of sediment into (accretion) and out of (erosion) an area of
study (sediment budget). Applied Coastal personnel use these data to
quantify regional and local changes in nearshore bathymetry to identify
trends in coastal/shelf sediment dynamics, and to evaluate the impact of
natural processes and human influences on a study area. Applied Coastal
personnel have conducted these kinds of studies along all U.S. coasts to
evaluate long- and short-term changes in coastal response to physical
processes in the nearshore zone, particularly as they relate to
tidal-influenced sedimentation patterns associated with inlets and
adjacent coastal reaches.
